proportions. The displays were not entirely confined to the 
Mines and Mining building, as might be naturally expected, 
but many were also in the other buildings. Even exhibits of 
the same character and by the same country or state were oc- 
casionally divided and housed in two or more buildings, in 
some instances quite a mile apart. The subject of mineralogy 
as here treated, being, perhaps, more scientific than economic, 
received only secondary consideration in the general plans for 
the exhibits in the Mines and Mining building; but it was, 
perhaps, better to display mainly the natural economic re- 
sources of the countries represented. Thus we found a large part 
of the first or ground floor of this building occupied chiefly 
with collections of ores and illustrations of the processes of 
mining and metallurgy. Almost every state and country had 
one or more collections of minerals, some of which were ar- 
ranged very systematically, but many of these were limited 
to purely economic exhibits. 
One of the most interesting collections was that exhibited 
by Mr. George F. Kunz, of New York, in the west gallery, 
representing the minerals occurring on Manhattan island, the 
site of New York city. Among the gems in this collection 
were beryl, garnet, moonstone, tourmaline in various colors, 
some good zeolites, specimens of epidote, cyanite, molybden- 
ite, etc. Mr. Kunz also exhibited his well known collection of 
meteorites. 
In the same west gallery was a collection of brilliant quartz. 
crystals, containing inclusions of anthracite, water, carbonic 
dioxide, etc., from Middleville, N. Y. There were also excel- 
lent exhibits by Messrs. English, Ward, Howell, and other 
dealers in minerals; and by the states of Colorado, Nevada, 
New York, and Ohio. 
It was surprising to see the great number of collections of 
gems. Diamonds, both cut and rough, were exhibited by New 
South Wales from several localities; but the best were from 
the Bingera district, exhibited by Prof. Liversidge, F. R. S* 
Other diamond exhibits were by Brazil, North Carolina, and 
Cape Colony, the latter very extensive and showing the 
various operations of diamond mining. New South Wales. 
showed the diamantiferous sand, and Cape Colony the so- 
called blue earth.
